Over the past few months the power door locks on my 2000 f150 Lariat 4x4 would go through periods where they wouldn't work. Over a couple of driving cycles they would return and work fine. Recently, they stopped operating all together...but the truck would mysteriously unlock itself when left alone. As a result I pulled the fuse. This weekend I replaced the chinese actuators (Set 2 or 3) with real Ford OEM ones from the dealer. Hoping that would be it. I also bought a new relay and played musical relays to see if that would do...Niether did. The truck beeps the lights turn on with the remote. After installing the 2 actuators they kept clicking over and over, forcing the door to unlock. I would push the lock down and it would pop right up. I did unplug each door switch thinking it was a stuck switch. But that also didn't do it. Could I have a stuck relay? Any ideas? I am at a loss to explain. Thanks

 

Do you have factory Remote Keyless Entry , or an aftermarket Remote Start installed ?

When you installed the after market ones, did you have to change the wiring to make them work ?

 

Hello, I have the factory keyless entry system. I am also the original owner. Thanks!
